Dreamweaver/DREAMWEAVER CS4

I'm Arturo Vazquez and I work for MC Research agency in Mexico City, I'm in charge of developing our website. I've almost finished it, nevertheless I have a problem with the Spry Horizontal Menu in Dreamweaver CS4, the specific problem I have, is that when I select a Menu or Submenu the font increase (I didn't want that), and also, and more important, the links don't seem to work very well, I mean, sometimes they work (when I reload de page) but sometimes they don't and in other cases they don't work at all.
